Eating spicy candy may dull the sensation of severe physical pain, according to a recent small study on human sensory perception. Researchers found that putting gelatin cubes infused with chili peppers in the mouth reduced people’s intense reactions to high-intensity laser heat applied to their hands, but it did not reduce the sensation of mild heat pain. The results of this study were published in the journal Physiology & Behavior. Capsaicin is the active chemical component that gives chili peppers their famous kick. When ingested, it binds to a specific type of receptor in the body known as TRPV1. These…

Men who naturally prefer to stay up late may be more susceptible to premature ejaculation later in life, and often experience more severe symptoms than men who rise early. Recent research has found that this association is partially related to lifestyle habits, highlighting how sleep preferences and daily activities can affect sexual function. This research Sexual medicine journal. Premature ejaculation is one of the most common sexual health conditions affecting men around the world. Doctors classify it into two main subtypes based on when symptoms begin. Lifelong premature ejaculation is present from the first sexual encounter. This condition, which can…

Iron and oxygen interact in many important processes throughout the human body. The most well-known example is hemoglobin. In hemoglobin, iron combines with dioxygen. This means that the two oxygen atoms have joined together, meaning that the oxygen is transported through the bloodstream. Iron also forms highly reactive compounds known as iron oxos. These compounds are involved in other biological functions, such as reactions carried out by liver enzymes that help break down drugs. Exploration of oxygen chemistry beyond iron Rice University chemist Raul Hernandez Sánchez wanted to know whether oxygen could form similar compounds with different metal groups near…

After a national election, voters whose party loses tend to have significantly lower general trust in other people in society. New research published in journal election research We suggest that this decline is particularly strong among voters who harbor deep negative feelings toward the opposing party. These findings provide evidence that the competitive nature of modern politics may weaken the everyday social structures that help communities function. Political scientists often distinguish between political trust and social trust. Political trust refers to the degree of trust that citizens have in government institutions, democratic processes, and elected officials. This type of trust…

French writer Marcel Proust famously recalled the vivid memories of his childhood when he heard the taste of madeleines. New research suggests there may be more to this type of reminiscence than just the brain. Signals from the digestive system may also help determine which food-related experiences become memories. The study, led by Scott Kanosky, a professor of biology in the USC Dornsif College of Letters, Arts and Sciences, shows that the gut may contribute to memory formation, especially when it comes to the experience of finding and consuming food. Published in nature communicationsthe study looked at the vagus nerve,…

For decades, scientists believed that photoreceptors in the retina primarily relied on adjacent supporting cells, known as the retinal pigment epithelium (RPE), to remove waste products. The RPE is still responsible for removing the worn tips of photoreceptors every day, but a new discovery from the University of Oklahoma reveals that photoreceptors also perform much of their own internal housekeeping. This research cell death and disease. Our study provides the first direct evidence that photoreceptors have a unique internal recycling system essential for their survival. Rather than relying solely on the RPE, photoreceptors use the cell’s recycling center, the…

A lack of data on prisoner characteristics gives an incomplete picture of who dies in prison and why, and may contribute to preventable deaths in custody, according to a new report. In the new report – “How documenting inequalities can reduce prisoner deaths.”a team of experts from the University of Nottingham has highlighted that equality data, including prisoner characteristics such as disability and indicators of socio-economic deprivation, is an essential foundation for evidence-based action to prevent deaths in custody. The research was part of the European Research Council-funded RECEDE project and was led by Philippa Tomczak, professor of criminology and…

University of Houston psychologists have received a $2.8 million grant from the National Institute of Child Health and Human Development to lead the first randomized clinical trial to examine whether remotely delivered parenting programs can improve healthy brain development in young children and support long-term mental health outcomes for premature infants. Researchers plan to investigate whether providing web-based support to parents during the critical weeks and months after premature babies are discharged from hospital enhances early brain development related to emotional and mental health. More than 1 in 10 babies in the United States is born prematurely each year, and…

The National Institutes of Health’s National Institute of Allergy and Infectious Diseases has awarded a new five-year, $2.4 million R01 grant to Jiahui Ding, Ph.D., assistant professor of obstetrics and gynecology in the C.S. Mott Center for Human Growth and Development at Wayne State University School of Medicine, to support research aimed at determining how viral infections during pregnancy reprogram the developing fetus’ immune system and influence lifelong susceptibility to infections. Maternal viral infections during pregnancy are associated with adverse pregnancy outcomes and long-term effects on offspring health. However, scientists do not fully understand how maternal infection alters fetal immune…

Hospitals should plan for rising supply chain costs in 2027, with prices in indirect spending categories such as IT, construction and even food projected to rise even faster than drug prices, Vizient warned in its latest forecast report. Vizient’s latest biannual report forecasts price inflation across the supply chain to be 3.39% in 2027, an increase of 0.61 percentage points compared to the forecast for the second half of 2026 and 12 months published in February. Jeff King, director of research and intelligence at Vizient, told Fierce Healthcare that the main drivers are the demand for AI and the rising…
